Santanu,
I don't know if the corganites and corgaspinites described by
Mazzone and Haggerty possess exsolution textures, but the the
assemblage (garnetąspinelącorundum) and bulk composition sounds like
a match
The reference is
Mazzone, P. and Haggerty, S.E. (1989) Corganites and corgaspinites:
two new types of aluminous xenoliths form the Jagersfontein
kimberlite pipe. Kimberlites and Related Rocks, Part 2. Geological
Society of Australia Special Publication, 14, pp. 795-808.
